The system receives a request to identify candidate documents pertinent to a document present in the document authoring application. A set of candidate documents is identified from a document library based on the pattern of events, a reuse score for each candidate document, a similarity score for each candidate document, and content in the document present in the document authoring application.

BACKGROUND

The subject matter disclosed herein generally relates to a special-purpose machine that analyzes a user's document and provides candidates documents in a user interface element, including computerized variants of such special-purpose machines and improvements to such variants. Specifically, the present disclosure addresses systems and methods for identifying and displaying candidate documents pertinent to a document present in a document authoring application.

A document authoring application (e.g., Microsoft Word™) is typically used to generate a document and provides the user with a list of recent files accessed by the document authoring application. The list of recent files may not be always be relevant to the user. As such, the user may have to manually search through his folders to identify content from previously generated documents that may be relevant to the document currently present in the document authoring application.

DETAILED DESCRIPTION

The description that follows describes systems, methods, techniques, instruction sequences, and computing machine program products that illustrate example embodiments of the present subject matter. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide an understanding of various embodiments of the present subject matter. It will be evident, however, to those skilled in the art, that embodiments of the present subject matter may be practiced without some or other of these specific details. Examples merely typify possible variations. Unless explicitly stated otherwise, structures (e.g., structural components, such as modules) are optional and may be combined or subdivided, and operations (e.g., in a procedure, algorithm, or other function) may vary in sequence or be combined or subdivided.

The present application describes a system and method for identifying relevant documents that are pertinent to a user of a document authoring application (e.g., Microsoft Word™, Microsoft PowerPoint™). In one example, the system uses a machine learning model to identify content (from other documents previously authored, edited, shared by the user, or shared with the user) with a high likelihood that the user will reuse the identified content in a document present in the document authoring application. The system then presents the candidate documents in a user interface element of the document authoring application.

In one example, the machine learning model evaluates attributes of a document to compute a score (e.g., a reuse score for ranking documents) for each document. Examples of attributes of documents include, but are not limited to, last accessed time of a document, document creation time, document file size and file type, timestamp a document was shared with the user, whether the document is located in a public or favorite folder, and timestamp of the last access by the user. In another example embodiment, the machine learning model is also based on a current behavior of the user copying content from one document and pasting the copied content to the document present in the document authoring application.

In another example embodiment, the system generates a document semantic similarity score (also referred to as similarity score) for each document. The similarity score is generated, for example, using a DSSM (Deep Semantic Similarity Model), where the feature inputs include: the file name, title, and the 200-character neighborhood around the insertion point (from the document present in the document authoring application), and the file name, title, and document summary (for each candidate document).

In one example, the user belongs to an enterprise. The enterprise represents an organization or groups of users associated with an organization. The users of the enterprise may make use of enterprise applications operating on client machines. Examples of enterprise applications include chat-based applications, email applications, document authoring applications, document editing applications, document viewing applications, document sharing applications, and other types of applications used by enterprises.

In one example embodiment, the present application describes a system and method for identifying relevant content from other documents and presenting candidate documents in a document authoring application. The system identifies a pattern of events from the document authoring application. The system receives a request to identify candidate documents pertinent to a document present in the document authoring application. A set of candidate documents is identified from a document library based on the pattern of events, a reuse score for each candidate document, a similarity score for each candidate document, and content in the document present in the document authoring application. The set of candidate documents is provided in a user interface element of the document authoring application. In another example embodiment, the system identifies the set of candidate documents from the document library based a score computed based on the pattern of events and the content in the document present. The score comprises, but is not limited to, a ranking score that is based on the reuse score and the similarity score. In one example, the similarity score is fed into a first machine learning model alongside other feature inputs (listed below) to generate the ranking score. A separate second machine learning model can be used to generate the similarity score. In other examples, other types of scores can be computed based on attributes of the pattern of events and attributes of the content in the document present.

As a result, one or more of the methodologies described herein facilitate solving the technical problem of searching for items that a user may not be aware. As such, one or more of the methodologies described herein may obviate a need for certain efforts or computing resources. Examples of such computing resources include processor cycles, network traffic, memory usage, data storage capacity, power consumption, network bandwidth, and cooling capacity.

FIG. 1 is a diagrammatic representation of a network environment in which some example embodiments of the present disclosure may be implemented or deployed. One or more application servers 104 provide server-side functionality via a network 102 to a networked user device, in the form of a client device 106. A user 132 operates the client device 106. The client device 106 includes a web client 112 (e.g., a browser operating a web version of an enterprise application), a programmatic client 108 (e.g., a client-side enterprise document application such as Microsoft PowerPoint™) that is hosted and executed on the client device 106. In one example embodiment, the programmatic client 108 includes a document reuse module 110 that identifies candidate documents with a high likelihood that the user 132 will copy and paste content from into a document present (e.g., being authored or edited) in the programmatic client 108 (or the web client 112).

For example, the document reuse module 110 generates a display of a user interface element (e.g., pane pop-up) that includes candidate documents (e.g., recommended or suggested documents, or relevant content from other documents) in the graphical user interface of the programmatic client 108. The candidate documents may include a set of documents from a library of documents. The library of documents may include documents that have been previously edited, accessed, authored, shared with or by the user 132. The library of documents may be stored in databases 130. In another example embodiment, the library of documents includes additional documents that have not yet been accessed by the user 132 or are yet unknown to the user 132. For example, the system has determined that the additional documents are relevant to the user 132 prior to the user 132 being aware of the additional documents or being shared to the additional documents.

In one example, the document reuse module 110 detects that the user 132 has opened the programmatic client 108. The document reuse module 110 identifies candidate documents based on a profile of the user 132 (e.g., user 132 is a new accountant), events of the programmatic client 108 (e.g., first time the user 132 is using the programmatic client 108, the programmatic client 108 is being operated on a Monday morning), and attributes of documents in the library of documents (e.g., most opened documents from new accounting employees on the first day of their job).

In another example embodiment, the document reuse module 110 detects that the user 132 is writing content for a new document. The document reuse module 110 identifies the content written by the user 132 in the programmatic client 108. The document reuse module 110 uses the identified content to identify candidate documents that the user 132 will most likely reuse portions of the content from the candidate documents in the new document. The document reuse module 110 displays the candidate documents in a new user interface (e.g., new pane) of the programmatic client 108. In another example, the document reuse module 110 uses the identified content to identify content from candidate documents. The document reuse module 110 displays the suggested content in the new user interface (e.g., new pane) of the programmatic client 108.

In another example embodiment, the document reuse module 110 triggers a pane pop-up that includes the candidate documents in response to the user's request to find documents with content relevant to the document currently present in the programmatic client 108. In another example embodiment, the document reuse module 110 learns from the user's behaviors (with respect to the programmatic client 108) and determines whether to trigger the pane pop-up at the programmatic client 108. For example, the document reuse module 110 automatically triggers the pane pop-up only on weekdays morning.

The document reuse module 110 may operate with the web client 112 and/or the programmatic client 108. In another example embodiment, the document reuse module 110 is part of the programmatic client 108 or web client 112. For example, the document reuse module 110 may operate as an extension or add on to the web client 112.

An Application Program Interface (API) server 120 and a web server 122 provide respective programmatic and web interfaces to application servers 104. A specific application server 118 hosts a document authoring application 124 and a document reuse engine 126. Both document authoring application 124 and document reuse engine 126 include components, modules and/or applications.

The document authoring application 124 includes a content creation application (e.g., Microsoft PowerPoint™, Microsoft Word™) that enables the user 132 to form content such as a presentation document, or a text document. In another example, the document authoring application 124 also includes a collaborative application that enables peer enterprise users to collaborate on a shared document. For example, the client device 106 may access the document authoring application 124 to view and edit a document that is shared with other peer users. Other examples of document authoring application 124 includes enterprise systems, content management systems, and knowledge management systems. The document authoring application 124 communicates with the programmatic client 108 on the client device 106. For example, the programmatic client 108 checks in with the document authoring application 124 and verifies a validity of a license or version of the programmatic client 108 on the client device 106. In another example embodiment, the programmatic client 108 includes at least one of a content creation application, a collaborative application, and a shared storage application.

In one example embodiment, the document reuse engine 126 communicates with the document authoring application 124 (or the document reuse module 110) to identify candidate documents based on a machine learning model that uses the content provided by the user 132 in the programmatic client 108 (or in the web client 112, or document authoring application 124) and other signals such as copy and paste activities of the programmatic client 108, profile of the user 132, attributes of the document currently edited in the programmatic client 108, features of documents in a library of documents previously authored, shared, edited by the user 132, or share with the user 132). The document reuse engine 126 communicates with the document reuse module 110 supported by the web server 122 to provide the candidate documents to the programmatic client 108. In another example, the document reuse module 110 includes functionalities of the document reuse engine 126. In another example, the document reuse module 110 includes components of the document reuse engine 126.

In one example embodiment, the web client 112 communicates with the document reuse engine 126 and document authoring application 124 via the programmatic interface provided by the Application Program Interface (API) server 120. In another example embodiment, the document reuse engine 126 sends the candidate documents to the document reuse module 110. The document reuse module 110 causes a display of the candidate documents in a pane pop-up based on current activities of the user 132 at the client device 106, current activities (or events) of the programmatic client 108, and a user profile of the user 132.

In one example embodiment, the document reuse engine 126 trains a machine learning model based on application events (activities of the user 132 on the client device 106 or the document authoring application 124) and features of documents from the library of documents. In another example, the document reuse engine 126 trains the machine learning model offline by first logging the information. The document reuse engine 126 uses the machine learning model to determine whether a document from the library of documents is relevant and includes content that is likely to be reused by the user 132. The document reuse engine 126 identifies a set of candidate documents and causes the document reuse module 110 (or the programmatic client 108 or the web client 112) to display a pane pop-up at the programmatic client 108 or the web client 112.

The application server 118 is shown to be communicatively coupled to database servers 128 that facilitates access to an information storage repository or databases 130. In an example embodiment, the databases 130 includes storage devices that store information to be published and/or processed by the document authoring application 124. For example, the databases 130 include a library of documents (e.g., documents that are shared with the user 132, shared by the user 132, accessed, authored, or edited by the user 132 using the web client 112 or the programmatic client 108).

Additionally, a third-party application 116 executing on a third-party server 114, is shown as having programmatic access to the application server 118 via the programmatic interface provided by the Application Program Interface (API) server 120. For example, the third-party application 116, using information retrieved from the application server 118, may supports one or more features or functions on a website hosted by the third party. For example, the third-party application 116 identifies activities of the user 132 on the programmatic client 108. The third-party application 116 provides the activities to the document reuse engine 126. The document reuse engine 126 identifies candidate documents pertinent to the user 132 based on the activities of the user 132.

FIG. 2 is a block diagram illustrating a document reuse engine 126 in accordance with one example embodiment. The event monitoring module 202 accesses user activities data from at least one of the programmatic client 108, the document authoring application 124, and the web client 112. In another example, the event monitoring module 202 combines user activities data from a combination of the programmatic client 108, the document authoring application 124, and the web client 112. In one example embodiment, the user activities data include user application activities within the programmatic client 108, the document authoring application 124, and the web client 112. For example, the user activities data include copy and paste activities (e.g., which previous document was used to copy in a present document, which part of the previous document was copied), file activities (e.g., which files were last opened by the user 132, which files were recently updated from a group folder shared with the user 132), the type of content (e.g., a PowerPoint slide) being created by the user 132, which features of the document authoring application 124, programmatic client 108, and web client 112 are being used by the user 132, and other user activities related to the document authoring application 124, the programmatic client 108, and the web client 112. The event monitoring module 202 provides the user activities data to the learning module 204.

In another example, the event monitoring module 202 identifies a user profile of the user 132 (e.g., user 132 is a new employee, is part of the accounting department group, and has used the programmatic client 108 less than five times). The event monitoring module 202 provides the user profile to the learning module 204.

The document library module 206 accesses a library of documents (that can be accessed with the programmatic client 108) stored in the databases 130. In one example, the library of documents includes documents (e.g., Word documents or PowerPoint documents) that the user 132 has previously viewed, edited, or authored. The library of documents can also include documents shared by the user 132 and documents shared with the user 132. In another example, the library of documents includes documents created by any employee of an enterprise associated with the user 132. In another example, the library of documents includes any documents publicly or privately accessible by the user 132. The document library module 206 accesses the documents and the corresponding attributes of the documents from the library of documents in databases 130, from another storage server, or from another computing device. The document library module 206 provides the documents and corresponding attributes to the learning module 204.

The learning module 204 operates using pattern detection algorithms and trained Machine Learning (ML) models to identify relevant documents (e.g., documents that the user 132 is likely to copy and paste content from). For example, the learning module 204 trains a machine learning model based on the signals from the event monitoring module 202 and the document library module 206 to determine whether a document is likely to be pertinent to the user 132. In one example embodiments, the learning module 204 analyzes events in the document authoring application 124 or programmatic client 108 to identify trends (e.g., a user has frequently chosen a particular document in the past). The learning module 204 accesses the above signals from event monitoring module 202 and the document library module 206. Using the information from the signals, the learning module 204 can identify trends. Based on the machine learning model, the learning module 204 can, in one embodiment, suggest candidate documents.

The learning module 204 provides the set of candidate documents to the candidate document user interface module 208. The candidate document user interface module 208 generates a display of the set of candidate documents in a user interface (e.g., a pane) of the programmatic client 108. In another example, the candidate document user interface module 208 identifies content (that the user 132 is likely to copy and paste) from the set of candidate documents in the user interface.

In another example embodiment, the event monitoring module 202 detects a request to identify relevant documents from the programmatic client 108. In response to the request, the learning module 204 identifies the set of candidate documents that are provided to the candidate document user interface module 208.

FIG. 3 is a block diagram illustrating a learning module 204 in accordance with one example embodiment. The learning module 204 includes a reuse score computation module 302, a similarity score computation module 304, and a candidate document ranking module 306.

In one example embodiment, the reuse score computation module 302 computes a reuse score for each document based on a trained machine learning model. The reuse score indicates a likelihood that the user 132 will re-use a content from a previously viewed document into a document present in the programmatic client 108. In one example embodiment, the reuse score computation module 302 trains the machine learning model based on a document selected by the user 132 from a list of candidate documents.

The machine learning model of the reuse score computation module 302 is trained by data from event monitoring module 202 and document library module 206. For example, the data includes labeled data (e.g., for each document, did the user select it?), input features for each document at the time it was shown to the user 132 (e.g., examples of input features are listed below), document groups (e.g., during a search, the user 132 is shown a list of documents, from which the user 132 selected one (or more); documents above the clicked document form the group; a ranking model is trained by adjusting the ranking until selected documents appear higher than non-selected docs in a test or cross-validation set).

Examples of input features of a candidate document include, but are not limited to: LastModifiedByAnyoneDate, CreatedDate, FileSize, FileType, LastSharedWithMeDate, IsPublicFolderFavorite, and LastAccessedByMeDate.

Another example of input features based on a user profile include, but are not limited to: TrendingAroundMeScore, FrequentlyUsedScore, AuthorRanklnMyTopNPeople, and LastSharerRankInMyTopNPeople.

Another example of input features based on the last 100 documents opened by the user, but are not limited to: OpenCountInLastHour, OpenCountInLastDay, OpenCountInLastWeek, OpenCountInLastMonth, OpenCountInLast3Months, OpenCountInLast6Months, OpenCountInLastYear, OpenCountTotal, and OpenCountThisDayOfWeek.

Another example of input features based on the last 100 documents modified by the user, but are not limited to: ModifyCountInLastHour, ModifyCountInLastDay, ModifyCountInLastWeek, ModifyCountInLastMonth, ModifyCountInLast3Months, ModifyCountInLast6Months, ModifyCountInLastYear, ModifyCountTotal, ModifyCountThisDayOfWeek.

In another example, the reuse score computation module 302 detects content copied from a prior document (e.g., shared document) into a current document (e.g., document present in the document authoring application 124). The reuse score computation module 302 checks what a zero-term query (e.g. a request to find similar documents without the user providing any search terms) would have looked like at the time the user 132 pasted. Using the list of documents that would have been shown to the user 132, the reuse score computation module 302 finds the document that the user copied from in the list and updates the feature values of the document selected by the user 132. All documents that appear above that document in the list would be negative examples (e.g., examples of documents that the user 132 skipped over and thus may not be as relevant). In one example, the feature values are updated when the document features are stored in a persistent store from which they are fetched for use at runtime. However, if the features are fetched directly at runtime, the feature values are not updated.

The following illustrates an example scenario: the user 132 has 100 documents (e.g., D1 to D100) in their shard (e.g., personal user space in the service). Initially, all 100 documents have null scores indicating that the score is not computed yet. When the user 132 opens and views document D17, the client device 100 sends a signal indicating the event (e.g., opening and viewing document D17) to the document reuse engine 126 to trigger the score computation algorithm. The score computation algorithm (e.g., reuse score computation module 302) computes the score by taking into account the input features listed above and assigns a score to each of the documents (e.g., D1 to D100). Since document D17 was viewed recently, the learning module 204 assigns a higher score (for example, 178). The score 0 is assigned to all other documents. After two days, the user 132 opens the document D53 and modifies it. This signal flows through the system and triggers the score computation algorithm again. The algorithm again computes the score of all the documents and this time assigns the score 168 to D17 and 182 to D53. The user 132 then launches the document reuse module 110 to reuse the documents. The documents D1 to D100 are displayed with D53 at rank 1 and D17 at rank 2 followed by rest of the documents.

In one example, the reuse score is computed prior to receiving the user's request or query for relevant documents. In another example, the reuse score is updated based on events such as the user 132's selection of a candidate document or the user 132's activities.

The candidate document ranking module 306 ranks the candidate documents from the library of documents based on their corresponding reuse score and identifies a top predefined number of documents (e.g., top 200 documents). The candidate document ranking module 306 provides the identified documents to the similarity score computation module 304. In another example, the reuse score computation module 302 uses a machine learning model for ranking documents. For example, the machine learning model can be based on boosted decision trees and the Learning to Rank cost function for the training of the algorithm. The machine learning model itself may be based on a decision tree (nested if statement), where the input feature values are numeric values, and the output score is also a numeric value.

The similarity score computation module 304 computes a similarity score for each document provided by the candidate document ranking module 306. The similarity score indicates a similarity between a document present in the programmatic client 108 and a corresponding document from the top predefined number of documents (e.g., top documents provided by the candidate document ranking module 306). In one example embodiment, the similarity score computation module 304 uses a DSSM algorithm to train a machine learning model and compute the similarity score. The similarity score computation module 304 uses, for example, the following feature inputs to the DSSM algorithm: From the user's document, the filename, title, and the 200 character neighborhood around an insertion point are appended together and input as the ‘content’; For each candidate document, the filename, title, and summary are used as the input ‘content’. One advantage of this approach is that it does not require downloading and parsing the document.

Those of ordinary skills in the art will recognize that other types of algorithms may be used to train the machine learning model to compute a similarity score. Other examples of algorithms include, but are not limited to, TF-IDF (Term Frequency—Inverse Document Frequency), Keyphrase Extraction—(Finding matches between the key phrases in the user document and the candidate document), Named Entity Extraction—(Finding matches between the named entities in the user document and the candidate document).

The following illustrates an example scenario: the user 132 creates a document D0 named “HVAC Systems Improvement.docx”. The document summary is as follows: “Submitted by Contoso Air Conditioning Solutions. Northwinds building of Mechanical Engineering has an outdated HVAC system. They have submitted a public requests for proposals from qualified vendors for the full system improvement. Our firm, Contoso Total Air Conditioning solutions, feel confident and wants to apply in order to meet and exceed the required service expectations for this bid.”

The user 132 has 100 documents (D1 to D100) in their shard. The following are examples are some of the documents:

D12: Contoso Workforce Expansion.docx. Summary—Contoso wants to expand its workforce by 30%. It proposes to start the expansion process before end of second quarter of this financial year. This documents lists the logistics related to the proposed expansion.

D19: HVAC Proposal.docx. Summary—This document provides costing details for HVAC Systems Improvement for Northwinds building of Mechanical Engineering.

D64: Contoso RFP 2019.docx. Summary—Contoso is making requests for proposal to various organizations like Northwinds building for upgrading their Air conditional systems.

The similarity score computation module 304 computes the similarity scores between the pairs (D0, D0, (D0, D2), (D0, D3), . . . , (D0, D100). Because D19 has more similarity with D0 for file name and summary, D19 is assigned the similarity score of 0.968. Because D64 has slightly lesser degree of similarity with D0, D64 is assigned the similarity score 0.892. Because there is not much similarity between D12 and D0, D12 is assigned the similarity score 0.023.

Once the similarity score computation module 304 computes the similarity score for each candidate document (e.g., top 200 documents), the candidate document ranking module 306 ranks the candidate documents by similarity score. In one example, the candidate document ranking module 306 identifies a set of candidate documents with top similarity scores (e.g., top 30 documents).

FIG. 4 is a flow diagram illustrating a method 400 for computing a reuse score for a document in accordance with one example embodiment. Operations in the method 400 may be performed by the document reuse engine 126, using components (e.g., modules, engines) described above with respect to FIG. 2. Accordingly, the method 400 is described by way of example with reference to the document reuse engine 126. However, it shall be appreciated that at least some of the operations of the method 400 may be deployed on various other hardware configurations or be performed by similar components residing elsewhere. For example, some of the operations may be performed at the document reuse module 110.

At block 402, the event monitoring module 202 identifies document authoring application events. At block 404, the event monitoring module 202 identifies output of trending analysis. At block 406, the learning module 204 trains a machine learning model based on a combination of the document authoring application events and the output of trending analysis.

Operations in the method 500 may be performed by the document reuse engine 126, using components (e.g., modules, engines) described above with respect to FIG. 2. Accordingly, the method 500 is described by way of example with reference to the document reuse engine 126. However, it shall be appreciated that at least some of the operations of the method 500 may be deployed on various other hardware configurations or be performed by similar components residing elsewhere. For example, some of the operations may be performed at the document reuse module 110.

At block 502, the document reuse engine 126 ranks the candidate documents based on their corresponding reuse score. At block 504, the document reuse engine 126 identifies the top candidate documents based on their ranking.

FIG. 6 is a flow diagram illustrating a method 600 for identifying top candidate documents in accordance with another example embodiment. Operations in the method 600 may be performed by the document reuse engine 126, using components (e.g., modules, engines) described above with respect to FIG. 2. Accordingly, the method 600 is described by way of example with reference to the document reuse engine 126. However, it shall be appreciated that at least some of the operations of the method 600 may be deployed on various other hardware configurations or be performed by similar components residing elsewhere. For example, some of the operations may be performed at the document reuse module 110.

At block 602, the learning module 204 determines feature inputs for a current document. At block 604, the learning module 204 identifies candidate documents based on corresponding reuse score. In one example, the learning module 204 identifies candidate documents based on time since the user last accessed the documents. At block 606, the learning module 204 identifies feature inputs for the top candidate documents.

These instructions (e.g., the instructions 1508), when executed by processors 1502, cause various operations to implement the disclosed embodiments.

The instructions 1508 may be transmitted or received over the network 1520, using a transmission medium, via a network interface device (e.g., a network interface component included in the communication components 1540) and using any one of a number of well-known transfer protocols (e.g., hypertext transfer protocol (HTTP)). Similarly, the instructions 1508 may be transmitted or received using a transmission medium via the coupling 1526 (e.g., a peer-to-peer coupling) to the devices 1522.
